Converting between datetime and Pandas Timestamp objects
提问by Amelio Vazquez-Reina
I have the following:
我有以下几点：
> date1
Timestamp('2014-01-23 00:00:00', tz=None)
> date2
datetime.date(2014, 3, 26)
and I read on this answerthat I could use pandas.to_datetime()to convert from Timestampsto datetimeobjects, but it doesn't seem to work:
我阅读了这个答案，我可以用它pandas.to_datetime()来转换Timestamps为datetime对象，但它似乎不起作用：
> pd.to_datetime(date1)
Timestamp('2014-01-23 00:00:00', tz=None)
Why? How can I convert between these two formats?
为什么？如何在这两种格式之间进行转换？

You can use the to_pydatetime method to be more explicit:
您可以使用 to_pydatetime 方法更明确：
In [11]: ts = pd.Timestamp('2014-01-23 00:00:00', tz=None)
In [12]: ts.to_pydatetime()
Out[12]: datetime.datetime(2014, 1, 23, 0, 0)
It's also available on a DatetimeIndex:
它也可以在 DatetimeIndex 上使用：
In [13]: rng = pd.date_range('1/10/2011', periods=3, freq='D')
In [14]: rng.to_pydatetime()
Out[14]:
array([datetime.datetime(2011, 1, 10, 0, 0),
datetime.datetime(2011, 1, 11, 0, 0),
datetime.datetime(2011, 1, 12, 0, 0)], dtype=object)

>>> pd.Timestamp('2014-01-23 00:00:00', tz=None).to_datetime()
datetime.datetime(2014, 1, 23, 0, 0)
>>> pd.Timestamp(datetime.date(2014, 3, 26))
Timestamp('2014-03-26 00:00:00')

Pandas Timestamp to datetime.datetime:
熊猫时间戳到 datetime.datetime：
pd.Timestamp('2014-01-23 00:00:00', tz=None).to_pydatetime()
datetime.datetime to Timestamp
datetime.datetime 到时间戳
pd.Timestamp(datetime(2014, 1, 23))
